Witrynaof calculations of the dependence between impurity con-centration and the energy-gap width. They used electric measurements in these experiments. In these papers the results of 5 different authors are shown. In regard to Ge, at low temperatures (4.2K), the energy-gap vs. impurity concentration dependence is shown in [3]. Witryna5 lip 2024 · This impurity will only be able to contribute three valence electrons to the lattice, therefore leaving one excess hole (see figure below). Since holes will "accept" free electrons, a Group 3 impurity is also called an acceptor. A semiconductor doped with an acceptor. An excess hole is now present.
